You do understand the complicated redstone sensors are actually to activate a circuit, not to check the current time, right?

What you can do with the redstone day/night sensors, for instance, is light up your camp using the redstone lamps, and wire them (underground) so that they're only powered when it's night using the sensor, and automatically turn off during the day.

There's a typo in your title. It should say "Amazingly remedial day/night sensor for people who suck at redstone so much they can't make a simple circuit to detect if it's day or night and completely disregards the whole point of a day/night sensor which is to send out a pulse when it is day or night but not the other instead of simply telling you"
